Adhesive composition

Claim 1

An improved adhesive composition consisting essentially of (1) an aqueous dispersion of a polymeric substance selected from the group consisting of a water-insoluble linear copolymer, and salts thereof, of about two to about four weight percent of an acid selected from the group consisting of itaconic acid, fumaric acid, and the dimer of methacrylic acid, about five to about 25 weight percent of a member selected from the group consisting of methyl methacrylate and acrylonitrile, and the balance of at least one ester of acrylic acid with an alcohol having from one to 18 carbon atoms, the copolymer having a T 1 between about -15° C. and +15° C. and a viscosity average molecular weight between about 50,000 to about 2,000,000, the salt being selected from the group consisting of those of ammonium, alkali metals and those formed with a water-soluble amine, the dispersion containing about 30 to about 55 weight percent of water and at least about 30 weight percent by weight of copolymer, (2) a rosin ester dispersion, and (3) a filler or fillers, said components being present in the following amounts: ______________________________________ Parts By Weight ______________________________________ Acrylic-Containing Polymer Dispersion 100 Rosin Ester Dispersion 20-150 Filler 25-400 ______________________________________
